A new open source handheld is launching on Kickstarter, the GCW Zero.
The Zero is more or less the successor to the GPH and Dingoo handhelds created by, Justin Barwick, a member of the Dingoonity forums.

The Dingoonity forums has a lot of info about the Zero including videos, pics and reviews by members that have already recieved units.
If you're a follower of the open source scene consider backing the Zero and help keep the scene alive!
